防火橋架的與橋架的規(guī)格有直接關(guān)系，橋架的規(guī)格越大橋架的越高。例如橋架的寬度相同，橋架高度越高越高，橋架的高度相同，橋架的寬度越寬，橋架的也越高。

The price of fireproof cable trays is directly related to the specifications of the cable trays, and the higher the specifications of the cable trays, the higher the price of the bridge frame. For example, if the width of the bridge is the same, the higher the height of the bridge, the higher the price. If the height of the bridge is the same, the wider the width of the bridge, and the higher the price of the bridge.

防火橋架彎通配件中的終端封頭和伸縮節(jié)也需要單獨提料。伸縮節(jié)默認(rèn)無蓋，如需要增加伸縮節(jié)蓋板需備注說明。有問題可以直接咨詢防火橋架廠家，會有人員接聽指導(dǎo)。

The terminal heads and expansion joints in the bending fittings of the fireproof bridge also need to be separately extracted. The expansion joint has no cover by default. If an expansion joint cover needs to be added, please note and explain. If you have any questions, you can directly consult the manufacturer of the fireproof cable tray, and there will be professional personnel to answer and guide you.

防火橋架的常用大規(guī)格有600*150mm、600*200mm、800*150mm、800*200mm、1000*200mm等。防火橋架敷設(shè)之前要按照項目方提供的電氣施工圖進(jìn)行現(xiàn)場測量，盡量采用的標(biāo)準(zhǔn)產(chǎn)品和工廠訂制件。

The commonly used large specifications of fire resistant cable trays include 600 * 150mm, 600 * 200mm, 800 * 150mm, 800 * 200mm, 1000 * 200mm, etc. Before laying the fireproof bridge, on-site measurements should be carried out according to the electrical construction drawings provided by the project party, and standard products and factory ordered parts should be used as much as possible.

防火橋架敷設(shè)的托盤和梯架應(yīng)該合理分段，避免兩節(jié)連接處跨墻或走樓洞。

The trays and ladders laid on fire resistant cable trays should be reasonably segmented to avoid crossing walls or building openings at the connection between the two sections.

此外山東電纜橋架廠家提醒您，防火橋架不同耐火等級代表著起火后橋架內(nèi)的電纜維持正常工作時間的長度，按照橋架標(biāo)準(zhǔn)分為三個等級，NI等級代表時間大于等于60分鐘，NII等級代表時間大于等于45分鐘，NIII等級代表時間大于等于30分鐘，用戶可以項目消防橋架防火性能要求來選擇對應(yīng)耐火等級。

In addition, Shandong cable tray manufacturers remind you that different fire resistance ratings of fire resistant trays represent the length of normal working time for cables inside the tray after a fire. According to the tray standards, they are divided into three levels: NI level represents time greater than or equal to 60 minutes, NII level represents time greater than or equal to 45 minutes, and NIII level represents time greater than or equal to 30 minutes. Users can choose the corresponding fire resistance rating according to the fire performance requirements of the project's fire resistant tray.

防火橋架的重量決定因素包括橋架的寬度、高度、厚度和密度，寬度越寬重量越大，例如200*50mm比100*50的橋架要重，高度越高重量越沉，例如100*100mm比100*50mm的橋架要沉，厚度越厚重量越大，例如200*100*1.2mm比200*100*1.0mm的橋架重量大。還有怎樣的疑惑或者需求，就來我們網(wǎng)站http://www.njjfsc.com咨詢吧！

The weight determining factors of a fireproof bridge include the width, height, thickness, and density of the bridge. The wider the width, the heavier the weight. For example, a 200 * 50mm bridge is heavier than a 100 * 50 bridge, and the higher the height, the heavier the weight. For example, a 100 * 100mm bridge is heavier than a 100 * 50mm bridge, and the thicker the thickness, the heavier the weight. For example, a 200 * 100 * 1.2mm bridge is heavier than a 200 * 100 * 1.0mm bridge. If you have any further doubts or needs, please come to our website http://www.njjfsc.com Consult!
